1206W4F4700T5E 产品概述

一、产品简述

1206W4F4700T5E 是 UNI-ROYAL(厚声)系列的一款贴片厚膜电阻,封装为 1206(3.2 mm × 1.6 mm)。标称阻值 470Ω,精度 ±1%,额定功率 250 mW,最高工作电压 200 V,温度系数(TCR)±100 ppm/°C,工作温度范围 -55℃ ~ +155℃。本器件适用于一般电子产品中的限流、分压、终端阻抗匹配及通用功能电路,兼顾成本与可靠性,适合大批量生产使用。

二、主要技术参数

  • 类型:厚膜电阻(SMD)
  • 封装:1206(3.2 mm × 1.6 mm)
  • 阻值:470 Ω
  • 阻值精度:±1%
  • 额定功率:250 mW(通常基准温度 70℃)
  • 最大工作电压:200 V
  • 温度系数:±100 ppm/℃(典型)
  • 工作温度:-55℃ ~ +155℃
  • 品牌:UNI-ROYAL(厚声)
  • 典型特性:耐焊接温度、机械强度良好,适合回流焊工艺

三、性能特点

  1. 成本效益高:厚膜工艺适合低至中等阻值精度要求的场合,制造成本较低,适合量产。
  2. 精度良好:±1% 精度满足多数模拟与数字电路对阻值稳定性的需求。
  3. 宽温度范围:工作温度达到 -55℃ 至 +155℃,可用于较宽的工业环境温度范围。
  4. 中等热稳定性:TCR ±100 ppm/℃,在温度变化时阻值漂移较小,适合常温至高温工作场合。
  5. 焊接兼容性:适用于常见回流焊工艺,耐焊接峰值温度(典型回流峰值 250–260℃)但建议按供应商工艺规范操作。

四、典型应用场景

  • 消费电子:电源限流、滤波网络、信号接口电阻
  • 工业控制:传感器电路、信号调理与分压
  • 通讯设备:终端匹配、电平限制
  • 仪器仪表:常规分流与偏置网络 (注:若需用于汽车电子或需特殊认证的场合,请在采购前确认具体产品是否通过相应资格认证。)

五、使用与焊接建议

  • 回流焊:建议遵照 J-STD-020 型回流曲线,峰值温度 ≤ 260℃,在峰值温度下的停留时间按制造商推荐(通常为数秒),避免重复高温循环导致可靠性下降。
  • 降额使用:额定功率为 250 mW(参考值),在高于 70℃ 的环境需按厂家提供的功率降额曲线使用;常见做法为从 70℃ 开始线性降额至最高环境温度。
  • PCB 布局:焊盘设计应考虑热分布与焊接可靠性,避免在焊盘附近留有过多应力集中点;若电流较大,适当加宽铜箔有助于散热。
  • 机械应力:贴装时避免对电阻施加过大弯曲或压应力,避免焊膏用量过多导致浮贴或热应力。

六、可靠性与质量注意事项

  • 长期稳定性:作为厚膜电阻,其长期阻值漂移与噪声性能相比金属膜类略逊,但在规范的温湿度和电应力条件下可保持稳定性能。
  • 环境适应:工作温度范围宽,但如需在极端潮湿、盐雾或腐蚀性气氛中长期使用,应做额外防护或选用相应等级产品。
  • 认证与合规:标准产品一般满足常规 RoHS 要求;如需无铅兼容、汽车级(AEC-Q)或特殊环境认证,请与供应商确认具体型号与认证文件。

七、采购与包装建议

  • 订购时请标注完整料号:1206W4F4700T5E,并确认包装形式(卷带/盘装)、数量与批次要求。
  • 大批量应用建议与 UNI-ROYAL 确认供货稳定性与认证资料;如需样品验证,请先安排样品测试回流焊、可靠性与温漂等关键项目。

总结:1206W4F4700T5E 是一款面向通用电子设计的高性价比厚膜贴片电阻,适用于多种限流与分压场合。在使用中注意按额定温度与功率降额、遵循回流焊工艺规范并结合实际电路热设计,可获得良好的性能与可靠性。若需更详细的电气曲线或可靠性测试报告,请联系供应商索取完整数据手册。

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
